PUR disc – cut to size

PUR polyurethane discs cut to size

PUR discs, also known as polyurethane discs, are an extremely versatile material used in a wide variety of industrial, commercial and technical applications. These discs offer an excellent combination of flexibility, robustness and resilience, which makes them the ideal choice for applications in the automotive industry, mechanical engineering, the construction industry and many other sectors. Their mechanical properties enable high resistance to abrasion and an exceptional ability to absorb impact, which makes them ideal for demanding applications.

Polyurethane discs are characterised in particular by their high restoring force and their ability to damp vibrations. This is particularly valuable in industrial applications where vibrations or impacts must be avoided. PUR discs also impress in outdoor areas thanks to their high resistance to weathering, which makes their possible applications even more diverse.

Below you will find detailed information on the properties, technical data and typical areas of application of PUR discs, which make them an indispensable material in various branches of industry.

Properties

Physical properties of PUR discs

PUR discs offer an impressive mixture of elasticity and stability. They are both impact-resistant and abrasion-resistant, which makes them ideal for applications where high mechanical stress plays a role. The material remains flexible even at low temperatures, which means it can also be used effectively in cold environments. The elasticity of PUR discs makes it possible to absorb strong impact loads and damp vibrations, which in turn increases the service life of the surrounding components.

Another important feature of PUR discs is their resistance to chemical influences. They are resistant to oils, greases and many chemicals, which makes them particularly suitable for industrial applications. In addition, they are UV-resistant, which means they can also be used outdoors without their physical properties being impaired.

Applications

Use in mechanical engineering

In mechanical engineering, PUR discs are frequently used as buffers or damping elements to protect sensitive machine components from vibrations and impacts. Their high elasticity and abrasion resistance make them ideal for moving parts and areas where mechanical stress occurs. PUR discs are also used as plain bearings or flexible supports to enable low-friction and low-noise movement of machine parts.

Automotive industry

In the automotive industry, PUR discs are used in many ways, in particular as damping elements to reduce vibrations and noise. They are used in chassis, engine mounts and other vehicle components to absorb impacts and increase driving comfort. Their resistance to oils and greases ensures that PUR discs work reliably even under demanding conditions in the vehicle sector.

Construction industry and building services

In the construction industry, PUR discs are used because of their insulating and damping properties. They are used as sound insulation to prevent sound bridges and increase living comfort. PUR discs are also suitable as flexible impact protection systems, for example in windows and doors, to minimise energy losses. Their high resistance to moisture also makes them an ideal solution for outdoor applications.

Model making and prototype development

PUR discs are also a preferred material in model making and prototype development. They are easy to machine and enable high dimensional accuracy, which makes them ideal for creating functional models. The flexibility of the material makes it easy to create even complex shapes, while the high stability ensures that these models can withstand realistic loads.

Are PUR discs weather-resistant?

Yes, PUR discs are weather-resistant. They offer high resistance to UV radiation, ozone and moisture, which makes them suitable for outdoor use.

How can PUR discs be machined?

PUR discs can be machined by processes such as sawing, milling or punching. They can also be cast or injection-moulded, which allows a high degree of flexibility in production and adaptation.

What are PUR discs particularly suitable for?

PUR discs are particularly suitable for applications in mechanical engineering, the automotive industry, construction and model making. Their ability to damp vibrations and their chemical resistance make them a versatile material for a wide range of technical applications.

Technical data

• Material: polyurethane (PUR)
• Hardness: different degrees of hardness from soft to hard (e.g. Shore A 20 to Shore D 70)
• Temperature resistance: between -30 °C and +80 °C
• Chemical resistance: high resistance to oils, greases and solvents
• Elasticity: high restoring force, ideal for impact and vibration damping
• Weather resistance: very good resistance to UV radiation, ozone and moisture
• Abrasion resistance: outstanding resistance to mechanical wear

Thanks to their wide range of hardnesses, PUR discs can be used in particularly versatile ways. The different degrees of hardness make it possible to adapt the material perfectly to the respective application, whether as a soft damping element or as a firm, stable bearing.
